Why don't many people run a 6 inch exhaust? It won't wreck my truck some how will it? And anyone else running a power max 3? I hit a bump real good and my positive battery cable came off didn't realize it till my truck started action ng funny then I lost my lights pulled over and hooked it back up everything fine but now my egt and boost are reading 0. Anyone know how to fix that?

 

the reason why no one runs a 6 in exhaust is because there is no point. a five inch exhaust will handle up to around 1200hp. and even then if you are worried about exhaust restriction, i hood stack would be the best way to go.

 

6" would be a tight squeeze in between the frame and transmission/transfer case. 5" is pretty snug.

Did the fuse powering you gauges pop?
